T all whom it may concern:

Be it known that I, JOHN M. STUOHLIK, a citizen of the Republic of Czechoslovakia, residing at Roundup, in the county of Musselshell and State of Montana, have invent ed a new and useful lmprovementin Dividers, of which the following is a specification.

This invention relates to improvements in 0 dividers.

It is an object of the invention to create 7 a divider of particular use for carpenters, cabinet makers, joiners, or the like, and to combine with this divider the leg of a T- square or similarimp'leinent whereby definite angles'may be laid out or the size of angles may be ascertained. I 7

It is also an Obj ect of the invention toprovide in combination with a pair of dividers, 2 an adjustable member which may be extended either at right angle or at any other suit-v able angle to one ofthe legs of the divider.

or which when in inoperative position' may be folded so as to extend parallel to said legs brings the combination tool into a compact shape, in which it will be placed in an ordinary tool box.

It is also an object of the invention to per- 33 mit the use of the tool as a divider, without necessitating the removal of the T-square. Other objects of the invention will become apparent by reference tothe following specification and the accompanying drawing, which shows an embodiment of the invention. V l

In the drawing: 7 I

'1 is a front elevation of the improved combination tool; and

Fig. 2 is an end elevation of the same. The divider comprises the legs 1 and 2, terminating in sharpened points and being pivotally connected to each other by means of head portions which are unitedby' a suitable hinge pin 3.- 'Any preferred form. of l the legs of the divider or. of the pivot, con"- nection may be selected. e

The leg 1 of the'divider serves for supporting, by means of a pivot -pin' 4, the leg to of a T-square 5, which may be provided with suitable graduation marks and which has an enlargement near the inner end. This enlargement has an arcuate slot 6 concentric with the axis of the pivotal support 4, and a straight slot 7 extends approximately like.

' throughthe whole length of the leg 5 paralQ lel tothe edge of theT-square and communi cates with the arcuate; slot 6. A holding screw 8 extends through the leg 2 of the divider andisprovidedwith. a fiathead which is held in a suitable countersunk opening,

this screw also projecting throughthe arcu- I ate-slot '6 when the divider is closed. A.

thumb nut 9 on this screw serves, for locking the T-square 5 in adjusted position.

The enlarged portion of the T-square is,

furthermore, provided with a pointer 10 a which in the rotation of the square about its pivot point 4 plays over an arcuate scale 11 on an enlargement12 of the divider leg 1. It is abvious, therefore, that the'angular relation of the extension 5, with respect to the divider, may be ascertained by reading the position of the. pointer 10, with respect a to the arcuate'scale, and that-the extension 5 may 'be folded'to occupy the position indicated, in dotted linesin Fig. 1, in which position the entire implement-canreadily be inclosedin a c'arpenters tool boxfor the The enlarged portion 12 of the divider legrl may be provided with openings 13 to facilitate the rapid adjustment of the legat certain angles as, for instance, 45 or 185, at which positions of the leg. one of the openings 13 will be in registry with an open ordinary way by spreading the legs l' and '2, the holding screw 8. will slide in the 1. A geometrical instrument comprising.

.ing 14 in the enlargement 1O of the leg 5.

l Vhen the divider is to be used in the V c0 1 longitudinal slot 7 of theleg 5 without ima divider having a pair of legs adapted to".

constitute the head of a T-square; a bar provided with a slot pivotally secured to one, of said legs intermediate its ends, and

adapted to constitute theblade of the T- municating with said arcuate slot] at apsquare; and means carried by the other of sald legs, and engagingfsaid slot, adapted to clamp said bar in any des red angular j pro- 7 1 proximately its middle; a threaded stud rigid with the other of said legs, engaging said I slots; and a clamping nut engaging said stud adapted to firmly hold said bar in any desired angular relation to said legs.

3. In a device of the class described the combination of a pair of pivoted legs one tioned apertures whereby said bar may be readily positioned at predetermined points about said pivot; and means carried by the other of said legs and engaging said slot,

for clamping said bar in any desired an gular relation to said legs.

4. In a device of the character described, the combination of a pair oi dividers, a straight edge bar pivotally mounted on one leg of said dividers and having a pointer projecting from said pivot in a direction opposite to that of the bar, said leg having an arcuate enlargement over which said pointer plays, the bar having an arcuate slot concentric with the pivot of the bar and a longitudinal slot communicating with said arcuate slot, and a clamping screw extending through the other leg of the divider into said slot.

' In witness whereof, I have hereunto subscribed my name this second day of Sep-v tember, 1920. JOHN M. STUCHLIK.
